The invention relates to combined chair and table articles of juvenile furniture, such as high chairs and feed-and-play tables, which are used by babies while being fed or while playing with small toys and other playthings.
It is my primary object to provide a baby's chair-table article with means for looking a food dish securely in position on the table thereof at feeding time to prevent it from becoming overturned when subjected to the babys natural inquisitiveness or immature handling.
Prior to the present invention, attempts have been made to devise means for removably afiixing a special food tray or dish to the regular table, 01' tray as it is sometimes called, at feeding time, but the resulting devices are bulky, complicated, unsightly and impractical in other respects. Moreover, when the food dish is removed, in each instance the table, or tray, presents open holes or protruding fastening means which render the table, or tray, unsuitable for play purposes.
In accordance with my improvement, 2. simple, shallow food dish of attractive appearance is secured temporarily in countersunk position in the regular table, or tray, by locking means located thereunder in a position inaccessible to the baby seated in the chair and which is of a construction capable of easy manipulation by an adult.
Another object of the invention is to provide means by which the feeding table may be converted readily into a play table that presents a smooth, uninterrupted and imperforate upper surface. To be more explicit, I have provided an articulated cover for the regular feeding table that may be maintained in an out of the way position in back of the chair frame when said regular table is being used for feeding and then may be swung into horizontal operative position overlying and resting upon the regular feeding table when the baby occupying the chair Wants to play with toys. The cover just mentioned, which serves to convert the feeding table into a play table, also has means inaccessible to the occupant of the chair by which it may be secured fixedly to the feeding table in operative position.
A further object is to provide the conversion table cover with means to seal the food dish which may be assembled with the feeding table at the time against spilling of its contents whenever it is desired to convert said feeding table into a play table temporarily in interruption of the feeding period. Due to this provision, it is thus practicable to permit intermittent feeding and play without removal of the food dish, which oftentimes is a great advantage. Additionally, the
specific dish sealing means employed serves to aid in automatically starting separation of the conversion cover from the feeding table upon release of the securing means for the former.
The foregoing and other objects, advantages and features of the invention will be more fully understood as the following specific description is read in connection with the accompanying drawings, in which:
Fig. 1 is a side elevation of a high chair embodying the invention, showing the play table conversion cover for the feeding table in inoperative out of the way position in full lines and in operative position covering the feeding table in broken lines; and Fig. 2 is a fragmentary plan view of the high chair, showin the play table conversion cover in operative position only and a food dish assembled with the underlying feeding table.

Fig. 13 is a fragmentary vertical section of a food dish havin its exposed upper face provided with a sanitary coating.
Referring now in detail to the drawings, wherein like reference characters designate corresponding parts in the several views, the improved feedin device and play table conversion means are shown as being incorporated in a babys high chair of conventional construction. It is to be understood, however, that it is within the scope of the invention to apply the invention to other types of juvenile seat-provided furniture such as baby tenders and feed-and-play tables.
In the illustrative embodiment, the high chair C comprises the usual long-legged frame f which supports the seatin arrangements including seat .9, backrest b, armrests a and footrest f. The usual articulated table, or tray, t is pivotally connected to backrest b by a substantially U-shaped yoke y whose side arms are of such length that said table or tray will rest upon the forward portions of armrests a, when swung into the operative position represented in Fig. l, in convenient location with respect to a child occupant of the seat.
Since the present invention is of such a nature structurally that it may be built into a conventional article of juvenile furniture with only minor alterations in the latter, it will be assumed in the present disclosure that the existing high chairs in the unsold stock of a manufacturer are to be modified for reasons of economy preliminary to incorporation of the invention in future produc-- tion.
As shown particularly in Figs. 6 and 7, table It is provided with a large diameter circular through hole 26 in the thinned intermediate area thereof that is bordered by rim 2 l. The only other alteration of table if that is required is provision of a preferably downwardly tapered small diameter latch hole 22 to which more specific reference will be made later herein.
The side wall of hole 28 is tapered downwardly to fit a dish-shaped socket member 23 when lowcred into position therein. In this applied position, the horizontal rim of socket member 23 is countersunk in the upper portion of hole 29 and secured permanently therein in suitable manner, as by adhesive means or concealed fasteners (not shown). The bottom wall of socket member 23 is centrally punched out to afford a circular finger access opening 24 surrounded by annular supporting ledge 25 for a purpose now to be described.
A food dish 26 is provided for use in feeding the occupant of the chair. This dish 26 is intended to fit within socket member 23 in such a manner that the rim and bottom wall of the dish will rest upon the rim and annular flange 25, respectively, of said socket member to prevent the side wall of the dish from becoming tightly wedged against the side wall of said socket member, it being desired that the dish may be rotated freely through a limited arc of adjustment in the socket member and subsequently removed by light upward finger pressure against its bottom wall exrted through access opening 2t. In other words, although food dish 2% is substantially identical in cross-sectional shape with socket member 23, the outside diameter of the former is not the same as that of the latter. Instead, the mean outside diameter of the dish is substantially equal to the mean inside diameter of the socket member.
The reason for making dish 25 rotatable with out binding friction in socket member 23 is to permit utilization of the simple locking means which has been chosen to prevent the chair occupant from lifting and upsetting the dish. As shown particularly in Eigs. 6, 7, 8, and 11, this locking means is of the bayonet slot and headed lug type. In this instance, flange of socket member 23 has been provided with diametrically opposed bayonet slots 2l--2l of arcuate form and the bottom wall of dish 26 has headed lugs 28-23 positioned to register with and engage the respec tive bayonet slots when the dish is seated in the socket member. Subsequent partial rotation of the dish will cause it to be locked in place and the means for doing this will be concealed below the feeding table in a location inaccessible to the chair occupant. It is believed that the degree of are of bayonet slots 21-41 shown in the drawings is sufficient for secure attachment of dish 26 under normal conditions of use, but it is to be understood that the arc may be increased or otherwise changed in practice without departing from the scope of the invention.
To facilitate manual rotation of dish 26 in the act of locking and unlocking it, the bottom wall of said dish is provided with a diametrically arranged downstruck ridge 29 which protrudes through finger access opening 28 in socket member 23 and thus affords a finger-hold or handle.
As shown in Fig. 11, the bottom faces of locking lug 28-28 and finger-hold 22 of dish 26 have been arranged horizontally flush to permit the dish to rest in a level position on any convenient flat horizontal supporting surface after the dish has been removed from feeding table t of the high chair so that any liquid contents remaining in the dish will not be spilled. If, however, it should be found to be preferable in future development to use some other form or disposition of locking means, dish 28 may be provided with crossed ridges 2929", as depicted in Figure 12, to insure a stable base.
The other feature of the present invention that makes it possible to convert feeding table f quickly into a smooth, imperforate play table consists of a conversion cover for said feeding table, This cover 38 is identical in horizontal outline with table it and is similarly articulated in its attachment to backrest b of high chair C by means of an additional yokemember 3!, which preferably is pivotally attached in coaxial relation to yoke 11 of table '6 (Figs. 1 and 2). Conversion cover 3-) may be swung freely between the inoperative depending position in back of chair frame 1 represented in full lines in Fig. l and the operative position shown in broken lines in Fig. l and in solid lines in Fig. 2. The upper surface of conver sion cover 3 is countersunk to afford a smooth, level play table surrounded by a low protective rim 32.
Since it frequently occurs that feeding from dish 2t while assembled with feeding table 3 will be interrupted to permit play with toys and the like on top of conversion cover it, means has been provided to seal the mouth of dish 26 and thereby prevent spilling of its contents in the event that the chair is rocked by violent play or other causes. The means which I prefer to employ for this purpose is a circular fiat sealing member 33 of yieldable, elastic or resilient material, such as soft rubher or the like, which is adhesively or otherwise united to the under face of conversion cover Sll in a position to register with dish 26 when said cover is swung into its horizontal operative position in covering relation to feeding table 15.
To secure conversion cover 30 releasably in operative position, a simple latch device t l of the spring spindle type has been located centrally beneath the front edge of said cover for engagement with latch hole 22 in feeding table t. Latch device 34 comprises rigid shank 35 that depends from cover 35! and articulated, spring-deviated (closed) latch member proper 36. Shank 35 is anchored in cover 38 and projects beneath the same to an extent substantially equal to the thickness of feeding table t for complete penetration of latch hole 22 therein. In order to permit such penetration, latch member 5?; must first be oscillated from its deviated latching position against the action of its spring (not shown) into alignment with shank 35. The tapered form of latch hole 22 facilitates initial penetration, when the tip of latch member 3% happens to be slightly out of precise axial alignment with said latch hole, and finally corrects the alignment to such a degree that the marginal edges of feeding table if and conversion cover 30 will match perfectly. After penetration, latch member 35 will be restored by its spring biasing means to operative, locking position perpendicular to shank 35, wherein it abuts the under face of feeding table t. In this position, latch member 36 will effectively latch cover 30 in operative position and will be inaccessible to the chair occupant. When it becomes desirable to release and lift cover 30 to restore feeding table to operative condition for its primary purpose, latch member 36 is manipulated on its pivot into align ment with shank 35 and then used as a handle, to push cover upward from its seat until it can be grasped securely at its edges and swung into the inoperative position in rear of the high chair frame 1 represented in full lines in Fig. 1.
When conversion cover 30 is clamped in its operative position shown in Fig. 6, elastic sealing member 33 will be compressed and thereby placed under tension. Consequently, subsequent release of latch means 34 by swinging latch member 33 into alignment with shank 35 will permit sealing member 33 to expand vertically and draw latch member 36 upward into latch hole 22. This starting action permits instant freeing of the finger grasp on latch member 36, so that thereafter all that is required is upward fingertip pressure on the end of said latch member to lift conversion cover 39 sufficiently to permit it to be grasped at its edges by the free hand.
As illustrated in Fig. 13, dish 26 may be provided on its upper, exposed surface with a coating of porcelain or baked enamel to improve the appearance and sanitary condition of the dish in use.
In the embodiment of my invention in articles of juvenile furniture to be produced in the future, metal or plastic material may be used in the fabrication of the feeding table or the conversion cover instead of the wood ordinarily used for that purpose. Similarly, plastic or other material may be used to produce the food dish and socket member, it being understood that I am not limited to the choice of any particular material.
The present disclosure of the invention is an illustrative example and it accordingly is to be understood that various changes, modifications and alterations may be made in this structural embodiment which do not constitute departures from the spirit and scope of the invention.
